SQEX admitting that XV won't and hasn't pleased everyone is also a good sign. Back during the seventh-gen era, they got burned too many times by trying to appeal to a broad market, or just assuming everyone would continue to love and respect their brands no matter where they took them or how long each entry took to make. High risk policy to say the least. That they've pulled XV and many of their general brands from the brink, turned XV into a critical and commercial success, and recognised that not ignoring video game niches can be profitable is (I think) a good sign.
But XV does try to please everyone, it is definitely a game that doesn't really commit to anything.
It's an open world game, yeah but it's open world is shite, they wanted to do it to appeal to a mass market
It tries to be an action RPG, worse combat than a lot of Square Action RPGs, not to mention the boss fights, then there is a the wait mode to appease the turn based fans
Story wise, it tries so hard to be Versus XIII, but it's not, it doesn't commit to that either, to the point where people have said yeah they should have just scrapped Versus and started fresh
XV is a game that tries to appease everyone, but doesn't do it well.
Persona 5 is niche, that is a game that doesn't try to please the lowest common denominator, it commits to it's vision, and sticks to it, doesn't try to be many things as once.
Hell Nier Automata does this, but applying that to XV? No.
